'respectively on 19, such cranks being so disposed as to be a quarter turn or ninety 'degrees 'aparti The: forward "ends 10f these pitmen are connected Y to crank portions of a shaft *27. This-shaft comprises 1 a hollow body portion, I as best shown=in Figu3g and 'at'one end, and formed integralwith the body p/ortion,=-is* acra'nk" arm 28, terminating in? a I journal P 29', upon which the forward end of thepitman 23" is rotatably mounted;' Formed 'upon the other end of the body of the hollow shaft 27 is a short stud 30, the edge of which is for the most part concentric with the axis of the shaft, but which also has a flattened portion, 5 as at31. Upon this stud 30- is mounted a bevel wheel 32,'the hub thereof being provided with a central opening of a shape to correspond to the shape of the stud, and hence such gear or wheel is. not only nonrotatably mounted," but is always necessarily so placed that a journal carried by it, and preferably formed integral with it, Will always stand in correct relation to the journal or pin 29 at the other end. The journal 5 or pin projecting fromthebevel wheel 32 is indicated by 33. The bevel wheel is held in place by a bolt 34:, the head of which fits in an angular socket, as shown in Fig. 3. in the end portion of the body of the shaft, such bolt projecting through said end and through the gear, and being held in place by a nut 35, a washer 36 being preferably interposed between the nut and the face of the gear. To the journal or pin' 33 the forward endof the pitman 24 is suitably connected. 37 indicates openings through the wall of the body portion of the shaft, such openings being located adjacent to the ends of such body. portion where they will be covered by the bearings17. Through these openings 37 lubricant contained within the hollow body will pass to keep the bearings properly lubricated. Such lubricant will preferably be of thick or heavy variety, and will be inserted in place through an opening in that end of the body that carries the arm 28, which opening is normally closed by a screwthreaded plug 38, as shown. A- pair of handles will, of course, be properly secured 40 to the frame of the machine so as to projectrearwardly therefrom, asusual, but I have not deemed it necessary to show the same in-connection with the machine illustrated. w

With a machine having its parts constructed and arranged as shown and de'-' scribed, the pitmen are'so' located as to be much freer from liability to injury than in the constructions ordinarily employed, for with the'side bars of the mainframelocate'd in relation tothe pitmen, as shown, they will, to a large extent, guard such pitmen from contact with obstructions that might damage them. Furthermore, by connecting the rear; ends of thepitmen to cranks that are located between the side barsv of the frame and the hub of the supporting wheel, a construction is provided that is not only 'mor compact, but very much stronger than where the cranks are at the outer ends of the axle and where each crank is only supported from one end. Such improved arrangement of the pitmen also enables the machine to be provided with a shorter crank-shaft for the forward ends of the pitmen, which also contributes to greater strength. Such forward crank-shaft is very simply and cheaply made, as it comprises but two main parts, namely, the body portion, with which is cast the crank portions 2829, and the gear wheel portion 32, with which is cast the journal or pin 33, and by making the body portion of such shaft hollow, a sufficiently large quantity of suitable lubricant can, be contained therein to insure the bearings being kept properly lubricated for a comparatively long time.

What I claim as my invention and desire to secure by Letters Patent is 1. A shaft for rotating the seed-dropping mechanism of a planter of the class described, said shaft comprising a hollow body adapted to contain a lubricant and having openings through the body for the passa e of such lubricant to the bearings of the shaft, a crank formed on one end of said body, and a gear secured concentrically upon the other end of said body, and having a crank-pin. thereon in predetermined correct relation to the crank at the other end of the shaft.

2. A shaft for rotating the seed-dropping mechanism of a planter of the class described, said shaft comprising a hollow body adapted to contain a lubricant and having openings through the body for the passage of such lubricant to the bearings of the shaft, a crank formed on one end of said body, a gear secured concentrically upon the other end of said body and having a crank-pin projecting from its outer face, and means for compelling engagement of said gear with said body only in'a predetermined position for insuring the correct relative arrangement of its crank-pin with respect to the crank at theother end of the shaft.

3. A shaft for rotating the seed-dropping mechanism of a planter of the class described, said shaft comprising a hollow-body adapted to contain a lubricant and having openings through the body for the passage of such lubricant to the bearings of the shaft and also having an end opening for inserting the lubricant in the body, a closure for said last-named opening, said body having a crank on one of its ends and a stud on the opposite end, and a gear non-rotatably secured on said stud, the axes of the hollow body and the gear being coincident and the gear being provided with a crank arranged in correct. predetermined relation to the crank at the other end of the shaft.

4. A shaft for rotating the seed-dropping mechanism of a planter of the class described, said shaft comprising a hollow body adapted to contain a lubricant and having openings through the body for the passage of such lubricant to the bearings of the shaft, said body having a crank formed on one of its ends and a stud onits other end, '130 and a gear mounted on said stud and havincr a crank-pin on its outer face, said stud an the opening in the gear that receives the stud being formed to compel the gear to 00- cupy a predetermined position so that the crank-pin thereon will stand in proper relative position with respect to the crank at the other end of the shaft, the axes of the hollow body and gear being coincident.

5. A shaft for rotating theseed-dropping mechanism of a planter of the class described, said shaft comprising a hollow body havin a crank formed on one of its ends and a stud on its other end, a gear non-rotatively mounted on said stud and having a crank-pin on its outer face, and a bolt located in the hollow body and extending through the end thereof and through the stud and the gear for securing the gear against movement endwise of the stud.
